Re: The Endings of Darren Aronofsky
I don't think it's shoehorning, as I'm not saying Aronofsky is using the endings to say the exact same thing, just something similar. In an earlier post I agreed with darthyoshi when he said Sara's ending doesn't completely fit. If we're looking at theme, then they're very different. I just think there are some similarities.
As for the misinterpretation, I think Sara chooses to stay with the dream instead of facing reality. Her last expression of the film is one of utter horror and panic before she suppresses it and goes back to happily embracing Harry. At that point she knows the dream is dead. It's been a false reality for a while, but the film shows us she's aware of it and chooses to live in that false world instead of deal with reality. To me, that's no longer a dream.
